Explore: Conduction Band

In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level, and thus determine the electrical conductivity of

electron from the valence band to the conduction band. The resulting conduction-band electron (and the electron hole in the valence band) are free to move within

the band gap of a semiconductor can be of two basic types, a direct band gap or an indirect band gap. The minimal-energy state in the conduction band and
